How well would a Western Mountaineering GWS BIson sleeping bag fit in this bivy? What about the OR Alpine Bivy? I'm a bit concerned given the girth of the sleeping bag.

Joel, I'm about 90% sure the specs listed for the Advanced bivy are a little off--the Advanced is a slightly bigger bivy than the Alpine (and the specs listed are the same). That said, the width is still not big enough to fit the Bison perfectly. The shoulder width is probably 2-4" short for the Bison. However, since you do have the pole system, the usable interior space is greater than a standard bivy and so the excess width of the bag should still fit in the bivy just fine so long as you are comfortable with a little less shoulder room than you are used too. I hope this helps!

I would not be too worried about fitting into either unless you are much taller than 6'6". the alpine bivy is 3" shorter than the advanced, other than that, the dimensions are the same. the advanced has a 2pole setup where the alpine has one (which is partially why the advanced weighs 5oz more).
